Clearly all engines are exactly the same barring the swept volume of the pistons. And brake specific fuel consumption isn't actually a measurement of how efficient an engine makes power from the fuel it's consuming, and thus the air it's consuming by virtue of the air fuel ratio. Is just a bullshit phrase thrown around by people.

Yeah yeah yeah. How much more horsepower for each LB/min of air ingested do you think an FA20 can do over the F20C? F22C? How about the F20C over the 4G63?
F20C, F22C, 4G63, 4B11... They ALL max out a GT3076 somewhere real close to 500whp. Despite being different engines. Surely they don't all have the same rod ratio, piston ring sealing, bore size, cooling efficiency, compression ratio. Hell, one of them makes 120hp/L. WITHOUT direct injection and continuously variable cam timing. Surely that one should be capable of 600whp from 52lb/min...
